June 1947 Mountbatten declares that partition will go ahead.
July 1947 British judge Cyril Radcliffe draws up the border between India and Pakistan. The hastily devised plan, using out of date maps, cuts the Punjab and Bengal in half, creating an east and west Pakistan separated by more than 1,500 km (930 miles) of Indian territory.
August 1947 Separate states of Pakistan and India are born. Pakistan’s population will be mainly Muslim; India’s will be Hindu.
September 1947 Within days of partition, some of the worst sectarian violence in India’s history occurs. Hindus, Muslims and Sikhs scrambling to get to their side of new borders clash, leaving an estimated one million dead.
